Description

  The present invention relates to a medium imaging apparatus that images a certificate such as a driver's license and a health insurance card as an image used for identity verification, and more particularly to a medium imaging apparatus applied to a contract apparatus used in a financial institution or the like.

  Conventionally, in a financial institution or the like, a contract device for making a contract such as a credit subscription or a loan with a customer is used. As the contract device, there are those shown in Patent Documents 1 and 2, for example. The contract device is installed in a store and operated by a customer who makes a contract. The contract device is connected to a management device installed in the center via a communication line. This management device is operated by an operator who examines a contract with a customer who operates the contract device.

  A customer who makes a contract with a contract device uses an application form in which necessary information such as an address, name, and telephone number is entered, and documents used for proof of identification such as a driver's license and a health insurance card (hereinafter referred to as an identification card). ) Place the book on the table. The contract device includes an imaging device that captures an image of a document placed on the mounting table, and transmits a captured image of the document captured by the imaging device to the management device via a communication line. The management device displays the captured image transmitted from the contract device. The operator confirms the application form displayed on the management device and the image of the identification card, etc., and inputs the judgment result to the management device to determine whether or not the contract with the customer who operates the contract device is permitted. . The management device transmits the determination result input by the operator to the contract device via the communication line. Based on the determination result transmitted from the management device, the contract device issues a contract, a membership card, etc. to the customer, notifies the contract not possible, and the like.

  In this way, in a system using a contract device, the identity of the identification card is not checked directly with the hand of the operator, but is confirmed by visual confirmation of the captured image of the ID card imaged by the contract device. ing. For this reason, even if the identity certificate is forged by copying, cutting and pasting, etc., there is a risk that the operator will not accept that the identity certificate has been forged and allow the contract. In particular, it is necessary to make it possible for operators to make accurate judgments about the authenticity of identification because it is an environment in which high-precision printed materials can be easily obtained due to recent technological advances in printers and copiers. . In some cases, when determining whether or not to permit a contract, not only the matters described on the front side of the identification card but also the items described on the back side may be required.

  In Patent Document 1, a reflected image and a transmitted image of a document are captured by a camera. A document is irradiated with a fluorescent lamp arranged above the document, and a reflection image from the document is captured by a camera arranged above the document. Also, (1) a transmission image from the back side of the document with a fluorescent lamp placed below the document is taken with a camera placed above the document, and a transmission image from the front side of the document with a fluorescent lamp placed above the document There are two methods: a method of taking an image with a camera arranged below the document, and (2) a method of taking an image with a single camera arranged above the document by directly reflecting the front surface of the document with two mirrors on the back side. This method clearly shows how to obtain transmission images on both sides of a document without turning the document upside down.

Further, Patent Document 2 describes a configuration for simultaneously capturing the reflected images of the front surface and the back surface of the identification card mounted on the mounting table with one camera.
JP-A-9-204464 JP 2000-358184 A

  However, in Patent Document 2, a reflector with a reflecting surface facing the mounting table is placed under a transparent mounting table on which an identification card is placed, and an identification light placed on the mounting table. The camera is oriented in such a way that the ID card placed on the mounting table is imaged obliquely from above so that the virtual image of the ID card projected on the reflecting surface of the reflector and the lower surface of the ID card enters the imaging area. It was the structure which attached. In this configuration, the captured image of the identification card imaged by the camera is distorted. For this reason, when the operator visually confirms the captured image of the captured identity card, whether the distortion generated in the captured image is a distortion caused by imaging from an oblique direction, or the forged ID card itself Therefore, there is a problem in that it is impossible to accurately determine whether or not it is a distortion of the ID, and as a result, the determination regarding the authenticity of the identification card is wrong.

  In the configuration described in Patent Document 1, it is not necessary to turn the document over when acquiring a transmission image, but it is necessary for the customer to turn over the document when acquiring a reflection image. For this reason, a customer's operation becomes complicated and the problem of causing the increase in the time which a contract requires arises. As for the transmission image acquisition method that does not need to be turned over, two cameras are required in the above (1), and there are problems such as an increase in the size of the entire apparatus and an increase in cost. There is a problem that the orientation of the camera must be changed between when imaging and when imaging the back side.

  An object of the present invention is to allow a single camera to simultaneously capture the front and back surfaces of this medium without turning over the medium placed at the placement position, and to obtain a captured image with reduced distortion. It is an object of the present invention to provide a medium imaging device that can perform the above-described process.

  The medium imaging apparatus of the present invention has the following configuration in order to solve the above problems.

A transparent mounting plate for mounting the medium;
A reflector having a reflecting surface facing the mounting plate formed in a V-shaped cross section;
A camera that images the mounting table from the front side on the opposite side of the reflector across the mounting plate,
The reflector has an arrangement in which one reflection surface faces the medium placement position on the placement plate and the other reflection face does not face the medium placement position on the placement plate.

  In this configuration, the medium is mounted on a transparent mounting table formed of transparent acrylic or the like. The surface on the reflector side of the medium placed at the placement position of the placement table is reflected by one reflection surface of the reflector facing this surface, and this is projected and projected on the other reflection surface of the reflector. The camera disposed on the opposite side of the reflector with respect to the mounting table directly images the surface of the medium mounted on the mounting table facing the camera, not facing the camera of the medium. A virtual image is captured in which the side surface is projected onto the other surface of the reflector. Therefore, the camera can simultaneously image the front surface and the back surface of the medium placed on the mounting table, and can suppress distortion in the captured image.

  The imaging area of the camera only needs to be large enough to simultaneously image the front and back surfaces of the medium placed on the mounting table.

  In addition, when the light source is turned on and the medium placed on the placement position is irradiated, the front and back surfaces of the medium placed on the placement table are simultaneously imaged to obtain an appropriate brightness. A captured image can be obtained.

  There may be provided a true / false determination unit for determining the authenticity of the medium from the aspect ratio, positional deviation, hue, and the like in the captured images of the front and back surfaces of the medium simultaneously captured by the camera. Determination data used for authenticity determination may be set in advance.

  Also, the illumination provided on the opposite side of the camera across the placement plate is turned on, the illumination provided on the same side as the camera is turned off, and a transmission image of the medium placed on the placement table is taken. A true / false discriminating unit that discriminates the authenticity of the medium may be provided based on the transmission image. The determination data used when determining the authenticity of the medium based on the transmission image may be set in advance.

  In addition, a viewing restriction film that restricts the viewing angle may be attached to the mounting plate to make it difficult to see the internal structure of the apparatus. In this case, it is preferable to attach a visual field control film on the surface of the mounting plate opposite to the medium mounting surface. The reason is that it is not damaged by friction with the medium.

  Furthermore, by forming a protrusion for restricting the placement position of the medium on the surface of the placement plate on which the medium is placed, the medium can be easily placed and operability can be improved.

  According to the present invention, it is possible to simultaneously image the front surface and the back surface of the medium mounted on the mounting table, and to suppress distortion in the captured image.

The automatic contract system includes a contract device 1 installed in a store such as a financial institution and a management device 2 installed in a center. The contract device 1 is a device operated by a customer who makes a contract such as a credit subscription or a money loan, and the management device 2 is a device operated by an operator who examines whether or not a contract requested by the customer is permitted. The contract device 1 and the management device 2 are connected via a communication line such as a public line or a dedicated line. Each contract device 1 can be connected to an arbitrary management device 2 via a communication line. The contract device 1 can transmit and receive audio, video, and the like with the management device 2 connected via a communication line.

  FIG. 2 is a diagram showing the appearance of the contract device according to the present invention, and FIG. 3 is a block diagram showing the configuration of the contract device. The contract device 1 includes a control unit 11, a document imaging unit 12, a customer imaging unit 13, a voice input unit 14, a voice output unit 15, a display unit 16, an operation unit 17, and a communication unit 18. ing. The control unit 11 comprehensively controls the operation of each part of the main body. The document imaging unit 12 images a document placed on the document table 12a. The detailed configuration of the document imaging unit 12 will be described later.

  The customer imaging unit 13 images a customer who uses the main body of the contract apparatus 1 with the video camera 13a. The video camera 13a is attached to the front of the main body so that the face of the customer who uses the main body can be captured. The voice input unit 14 includes a microphone 14a (hereinafter simply referred to as a microphone 14a) attached to the front of the main body, and collects customer's voice using the microphone 14a. The voice input unit 14 processes the voice collected by the microphone 14a as input voice. The audio output unit 15 includes a speaker 15a attached to the front of the main body, and emits sound from the speaker 15a. The sound emitted from the speaker 15a is a message such as an operation guidance stored in the main body or a voice message transmitted from the management apparatus 2 via a communication line.

  The display part 16 has the indicator 16a attached to the main body front. The operation unit 17 has a touch panel 17a attached to the display surface of the display 16a. The display unit 16 displays an input operation screen or the like on the display 16a, and the operation unit 17 detects a pressed position of the touch panel 17a. The control unit 11 determines the customer's input operation based on the input operation screen displayed on the display 16a by the display unit 16 and the pressed position of the touch panel 17a detected by the operation unit 17. The communication unit 18 is a captured image of the document imaged by the document imaging unit 12, a customer face image captured by the customer imaging unit 13, a customer voice received by the voice input unit 14, and a customer received by the operation unit 17. The contents of the input operation and the like are transmitted to the management apparatus 2 connected via the communication line, and the voice transmitted from the management apparatus 2 and instructions to the main body are received.

  Although not specifically shown, the contract device 1 includes a document collection unit that collects application forms and the like and collects them, and an issue unit that issues contracts, membership cards, and the like on which contract contents are printed. .

  Here, the document imaging unit 12 will be described in detail. 4 and 5 are diagrams illustrating the configuration of the document imaging unit. FIG. 5 is a cross-sectional view in the AA direction in FIG. The document imaging unit 12 corresponds to the medium imaging device according to the present invention. Here, the document imaging unit 12 that images a driver's license will be described as an example of the identification card. An opening 41 is formed in the document table 12a. The opening 41 has a length in the width direction that is slightly longer (about 1 to 2 cm) than the length in the lateral direction of the driver's license, and the length in the depth direction is 2 times the vertical length of the driver's license. It is slightly longer (about 2-3 cm) than double. The width direction of the opening referred to here is the same direction as the width direction of the apparatus main body, and the depth direction is the same direction as the depth direction of the apparatus main body.

  A plate-like acrylic plate 42 is attached to the lower surface of the opening 41 to block the entire opening 41. The acrylic plate 42 is transparent. The acrylic plate 42 corresponds to the mounting plate referred to in the present invention. In addition, a visual field restriction film 43 is attached to the entire lower surface of the acrylic plate 42. The viewing restriction film 43 has a characteristic that the other side of the viewing restriction film 43 can be seen when viewed substantially from the front, and the other side of the viewing restriction film 43 cannot be seen when viewed from a certain angle. It is.

  The document imaging unit 12 includes a camera 31 that images a driver's license placed on the acrylic plate 42. The camera 31 is attached directly above the acrylic plate 42 so as to capture the driver's license placed on the acrylic plate 42 from the front. The imaging area of the camera 31 has a size including the entire opening 41 of the document table 12a. The document imaging unit 12 includes a reflector 32 that faces the camera 31 with an acrylic plate 42 attached to the opening 41 of the document table 12a interposed therebetween. The reflector 32 has a configuration in which two mirrors 32a and 32b are combined in a V shape, and the angle formed by the two mirrors 32a and 32b is 90 °. The reflecting surfaces of the two mirrors 32a and 32b are surfaces facing the opening 41 of the document table 12a. The mirror 32a is located on the front side of the main body, and the mirror 32b is located on the back side of the main body. The widths of the mirrors 32 a and 32 b are substantially the same as the width of the opening 41. The reflector 32 is attached so that the joint between the mirror 32 a and the mirror 32 b is located at the approximate center of the opening 41 in the depth direction. The length of the reflector 32 in the depth direction is substantially the same as the length of the opening 41 in the depth direction.

  Further, the document imaging unit 12 includes a light source 33a that illuminates the acrylic plate 42 from above, a light source 33b that illuminates the acrylic plate 42 from below, and a lighting control unit 34 that individually controls lighting of the light sources 33a and 33b. ing. The light sources 33a and 33b are auxiliary light sources when the camera 31 images a driver's license placed on the acrylic plate 42.

  The document imaging unit 12 having the above configuration places the driver's license imaged by the camera 31 close to the front side of the main body or the back side of the acrylic plate 42. That is, the mounting position of the driver's license is set to a position facing only one mirror 32a (or 32b) of the reflector 32. Therefore, when placing the driver's license on the acrylic plate 42, the customer must place the driver's license so as not to face the two mirrors 32a and 32b. The back surface (surface on the reflector 32 side) of the driver's license placed at the placement position (here, the front side of the main body of the acrylic plate 42 will be described as the placement position) is a mirror 32a facing the driver's license. It is reflected and projected to the other mirror 32b. For this reason, when both the light sources 33a and 33b are turned on and an image is taken by the camera 31, as shown in FIG. 6, the front and back reflection images of the driver's license can be taken simultaneously. The reflection image on the front surface of the driver's license is an image directly captured by the camera 31, and the reflection image on the back surface is a virtual image projected on the mirror 32b. As described above, the view restriction film 43 is attached to the lower surface of the acrylic plate 42. However, since the camera 31 is attached so as to capture the driver's license from the front of the acrylic plate 42, the projection is projected onto the mirror 32b. It is possible to take a virtual image on the back of the driver's license. Moreover, since the camera 31 images a driver's license from the front, distortion in the captured image is suppressed. Moreover, in the captured image imaged with the camera 31, the image of the back surface of a driver's license is reversed upside down and becomes small compared with the surface.

  The camera 31 has a depth of focus that allows the front and back surfaces of the driver's license to be imaged to a certain degree. Further, since the customer views the acrylic plate 42 at a certain angle, the reflector 32 attached below the acrylic plate 42 is hardly visible. Therefore, it is difficult for the customer to notice that the front and back surfaces of the driver's license placed on the acrylic plate 42 are imaged.

  Further, the document imaging unit 12 images the driving license placed on the acrylic plate 42 in a state where the light source 33a is turned off and the light source 33b is turned on, thereby transmitting the driving license from the back surface. An image (see FIG. 7) can be obtained. At this time, a virtual image of the back side of the driver's license projected on the mirror 32b can be taken simultaneously. In the transmitted image, a watermark of the captured driver's license appears. Further, the document imaging unit 12 images the driving license placed on the acrylic plate 42 in a state where the light source 33a is turned on and the light source 33b is turned off, thereby transmitting the driving license from the surface. An image can be obtained. This transmission image is a virtual image projected on the mirror 32b. At this time, a reflection image of the surface of the driver's license can be taken simultaneously. If a transparent image is used, the presence or absence of a watermark, the presence or absence of cut and paste, and the like can be determined.

  Next, the operation of the contract device 1 in this automatic contract system will be described. FIG. 8 is a flowchart showing the operation of the contract device. When the customer performs an input operation for starting contract processing, the contract device 1 starts the processing illustrated in FIG. The input operation related to the contract start process can be performed by pressing a predetermined position on the touch panel 17a. At this time, a menu screen is displayed on the display 16a, and the customer can easily determine which part of the touch panel 17a should be pressed to start the contract process.

  The contract device 1 first connects to the management device 2 via a communication line (s1). Then, the contract device 1 starts the customer imaging by the video camera 13a in the customer imaging unit 13 (s2). The contract device 1 transmits the customer image captured by the video camera 13a to the management device 2 via the communication line. The management device 2 displays the customer image transmitted from the contract device 1 on the display. Therefore, the operator who operates the management apparatus 2 can confirm the customer who is operating the contract apparatus 1 with an image. An operator operating the management device 1 requests the customer to place a driver's license on the acrylic plate 42. The operator makes this request, for example, by voice. Specifically, the operator uses a microphone to input a voice saying “Customer, please place driver's license on acrylic board 42” to management device 2. The management device 2 transmits the input voice to the contract device 1 via the communication line. In the contract apparatus 1, the voice output unit 15 outputs the voice uttered by the operator from the speaker 15 a.

  When the processing relating to s <b> 2 is completed, the contract apparatus 1 starts document imaging in the document imaging unit 12. First, the contract apparatus 1 turns on the light sources 33a and 33b by the lighting control unit 34 (s3), and starts imaging by the camera 31 (s4). The contract device 1 transmits an image captured by the camera 31 to the management device 2 via a communication line. At this time, the contract device 1 transmits the captured image in the document imaging unit 12 and the captured image in the customer imaging unit 13 to the management device 2, and transmits these images in a time division manner. The management device 2 may be configured to selectively display the images transmitted from the contract device 1, or may be configured to display both images by dividing the screen.

  The operator who operates the management device 2 checks the image transmitted from the contract device 1 and determines whether or not the customer places the driver's license at an appropriate position on the acrylic plate 42. In short, in the image captured by the camera 31, the operator can obtain a customer's license as long as the entire image is captured without the front and back surfaces of the driver's license overlapping. Determines that the driver's license is placed at an appropriate position on the acrylic plate 42. When the operator determines that the driver's license is not placed at an appropriate position, the operator requests the customer to correct the placement position of the driver's license. This request may be made by voice in the same manner as the request for placing the driver's license described above. When the operator determines that the driver's license is placed at an appropriate position on the acrylic plate 42 and the front and rear surfaces of the driver's license are properly captured, the operator instructs the contracting apparatus 1 to capture a transmission image. Perform input operations. The front and back reflection images of the driver's license obtained here are the images shown in FIG. 6, and these images are recorded and stored in the management device 2. In response to this input operation, the management apparatus 2 transmits a transparent image capturing instruction to the contract apparatus 1. Moreover, as shown in FIG. 6, since the reflection image of the front surface of the driver's license and the reflection image of the back surface are inverted, when the captured image is displayed on the management device 2, Image processing for displaying the reflected image by inverting the top and bottom may be performed. Further, the contract apparatus 1 may be configured to transmit the image to the management apparatus 2 after performing image processing for inverting the top and bottom of the reflected image on the back surface.

  When the contract apparatus 1 receives the transmission image capturing instruction from the management apparatus 2 (s5), the contract apparatus 1 turns off the light source 33a (s6). At this time, the contract apparatus 1 does not turn off the light source 33b. As a result, the document imaging unit 12 captures a transmission image from the back side of the driver's license shown in FIG. 7 and transmits this transmission image to the management device 2. When the operator confirms that the transmission of the transmission image from the back side of the driver's license has been completed, the operator performs an input operation for notifying the contract apparatus of the completion of the imaging. In response to this input operation, the management device 2 notifies the contract device 1 of the completion of imaging of the driver's license. The management device 2 records and stores the transmission image from the back side of the driving license obtained at this time in association with the reflection images of the front side and the back side obtained previously.

  When the contract device 1 is notified of the completion of imaging of the driver's license from the management device 2 (s7), the contract device 1 stops imaging of the document in the document imaging unit 12 (s8). In s8, the camera 31 is stopped and the light source 33b is turned off. In addition, guidance is provided for requesting the customer to receive a driver's license (s9). The guidance concerning s9 may be performed by voice output in the voice output unit 15 or may be performed by display output in the display unit 16. As a result, the customer receives a driver's license.

  The operator confirms the front and back reflection images and the transmission image from the back side of the driver's license acquired in the above-described process in the management device 2, and whether the driver's license captured this time has been forged. Judge whether. As described above, since the camera 31 images the driver's license from the front, distortion in the captured image is suppressed. In addition, since a transmission image from the back side is also obtained, it can be relatively easily determined whether or not the driver's license is forged by cutting and pasting the photographic part. Further, by comparing the customer imaged by the customer imaging unit 13 with the photograph of the driver's license, it can be confirmed whether the customer and the person of the photograph of the driver's license match. When it is determined that the contract with the customer is permitted, the operator performs an input operation for permitting the contract, and when the operator determines that the contract with the customer is not permitted, the operator performs an input operation for disapproving the contract. The management device 2 notifies the contract device 1 of the contract permission or contract disapproval input by the operator.

  The contract device 1 waits for a contract permission or non-permitted notification from the management device 2. When the contract permission is notified, the contract device 1 determines that the contract is permitted in s10, and includes a contract including the issuance of a contract document. Processing is performed (s11), the line with the management apparatus 2 is disconnected (s12), and this processing ends. In s11, an address entry, signature, seal, etc. are made on the contract issued and printed, and this is placed on the document table 12a. Further, the contract device 1 starts image capturing of the document by the document image capturing unit 12, images the contract placed on the document table 12 a, and transmits the captured image of the contract to the management device 2. The operator confirms whether or not the description of the user in the contract document is incomplete in the management device 2, and if there is incomplete, instructs the correction. This instruction may be performed by voice as in the above-described request for placing the driver's license. If there is no deficiency in the contract, the operator performs an input operation to instruct the contract apparatus 1 to collect the contract. When the contract device 1 is instructed to collect the contract, the contract device 1 collects the contract and issues a card or the like as necessary. Regarding the collection of the contract, a configuration for automatically collecting the contract placed on the document table 12a may be provided, or from the collection port forming the contract to the customer to the main body. You may make it insert. Further, the contract device 1 shifts the document imaging unit 12, the customer imaging unit 13, and the like to a stopped state in s12.

  In addition, when the contract device 1 is notified that the contract is not permitted, the contract device 1 determines that the contract is not permitted in s10, executes the processing related to s12 without performing the processing related to s11, and ends this processing. To do. At this time, the contract device 1 notifies the customer that the contract cannot be made.

  Thus, in the contract apparatus 1 according to this embodiment, not only the reflection images of the front and back surfaces of the driver's license can be simultaneously captured, but also distortion in the captured image is suppressed. Therefore, it is possible to reduce the possibility that the operator makes a mistake in the determination of forgery by confirming the captured image. Further, since the reflected images of the front and back surfaces of the driver's license can be taken without turning over the driver's license, the time required for contract processing with the customer can be sufficiently suppressed, and the processing efficiency is not lowered.

  In the above-described embodiment, the identification card used by the customer is the driver's license. However, another certificate such as a health insurance card may be used. Further, the document imaging unit 12 obtains the reflection image from the back surface after obtaining the reflection image of the front surface and the back surface, but the order of obtaining the captured image may be any order. In addition, although the reflection image on the front surface and the back surface is obtained at the same time, the transmission image from the back surface and the reflection image on the back surface may be obtained at the same time. In this case, a reflection image of the surface may be taken separately. Alternatively, the light source 33a may be turned on and the light source 33b may be turned off, so that a reflection image on the surface and a transmission image from the surface may be captured simultaneously.

  Moreover, since the visual field control film 43 is affixed to the lower surface of the acrylic plate 42, that is, the surface opposite to the side where the driver's license is placed, it is not damaged by friction with the driver's license.

  Further, as shown in FIG. 9, the image of the driver's license (reflected images of the front and back surfaces and the reflected image from the back surface) captured by the camera 31 is processed in the document imaging unit 12, and the authenticity of the driver's license is verified. An image processing unit 35 may be provided. For example, in the reflected images of the front and back surfaces, the relative displacement of the imaging position, the size ratio, etc., are detected to determine the authenticity, or the transmitted light is used to significantly change the amount of transmitted light May be detected, and a process of determining authenticity may be performed. The reference data used for the authenticity determination may be set in advance.

  In this case, it is only necessary to finally determine whether or not the contract is permitted based on the authenticity determination by the image processing and the notification regarding the contract permission from the management apparatus 2. Specifically, the contract may be permitted only when the management device 2 is notified of the permission of the contract and it is determined that the image processing is not forgery, and the contract is not permitted in other cases.

  Furthermore, as shown in FIGS. 10A and 10B, a protrusion 42a may be formed on the surface of the acrylic plate. The protrusion 42 a is formed at the approximate center of the acrylic plate 42 in the depth direction. That is, the acrylic plate 42 is provided at a place where the placement of the driver's license is separated. Therefore, the protrusion 42a can easily perform alignment when placing the driver's license, and can improve the operability of the customer.
